Sir/madam,,
The cbse maths board paper 2018 had a faulty question. The question no. 25 of set-2 code30/2.
The question is: "prove that, in a right triangle, the square on the hypotenuse is equal to the sum of the squares on the other two sides." clearly the question is ambiguous as it says "square on the hypotenuse" and not "square of the hypotenuse." so we cant prove pythagoras theorem here. (Maybe it is a typing mistake as it should be "of").
However if we assume that the question is saying that the square are on the hypotenuse and on the other sides so we should prove that the area of the square on the hypotenuse is equal to the sum of the area of the squares on the other sides, but again the word "area" is missing.
So, i kindly request cbse to look forward in this matter and evaluate the copies accordingly and award grace marks to those students to those students who attempted that question.
